$146M DRAINED FROM TWO EXCHANGES IN 24 HOURS EXTENDS FOUR-DAY HACK STREAK

Summary from the TLDR Crypto newsletter

Mercado Bitcoin, Brazil's largest centralized exchange, lost $40M in an exploit on November 2, while an unnamed EU-based exchange lost $106M the same day, bringing the combined single-day custodial loss to approximately $146M. Both incidents fall within a four-day window that also includes what market observers are calling the largest exploit on record, raising questions about a coordinated attack vector or shared infrastructure vulnerability across venues. The cluster puts renewed pressure on CEX hot wallet exposure and cross-jurisdictional key management practices.
